No. 12. Ehuria quadrigeminata Say, is mentioned in Dr. Packard's Bulletin as 

 "issuing from hickory trees in July, common. (McBride.)" 



It is one of the longicorn beetles, and is about nine-tenths of an inch long, with a 

 pale yellowish brown body. On the thorax are two black tubercles above, placed trans- 

 versely, and a short spine on each side. On each wing case^there are two double short 

 lines of a yellow colour, and slightly elevated. The tip is two spined, the exterior spine 

 being longest. 



No. 13. Heteracthes quadrimacidatus Newm., was bred from branches of hickory by 

 Dr. LeConte. This species belongs to the same family of beetles as that last referred to, 

 but I am unable to describe it, as I have neither beetle nor description. It is, however, of 

 very elongated form, the thorax being long and cylindrical. Antennae long and slender ; 

 eyes large and coarsely granulated. The name signifies "four- spotted." 



No. 14. Ohrium rubrum Newm., is a delicate little beetle, about one- fourth of an 

 inch in length, and of a reddish colour, as its name implies. The thorax is cylindrical, 

 with a small prominence on each side. The legs and antennae are slender, the latter 

 being as long as the body. I have only taken one specimen,, which was captured on 

 hickory foliage on 12th July. 



No. 15. Molorchus himaculatus Say, is very frequently found on flowering shrubs 

 during June and July, and differs from nearly all our Oerambycidae in having the wing 

 covers only half as long as the abdomen. It is a very slender beetle, one-third of an 

 inch in length ; black, with the head and thorax strongly punctured ; the abbreviated 

 elytra having each a yellowish dash almost parallel with the inner margin. The 

 antennae and legs are brownish ; the former being much longer in the males. One of 

 the species bred by Dr. LeConte from hickory twigs and branches. 



No. 16. Stenosphenus notatiis (Oliv.), is recorded by Kiley as having been cut from 

 hickory w^ood in March. It is closely allied to the beetle next to be described, but 

 differs from it structurally in some particulars, as, for instance, in having the elytra 

 truncated at the tip, and terminating in two spines. The thorax is rounded, without 

 spines or tubercles ; the antennae of the females are about as long as the body ; those .of 

 the males longer ; legs rather short. 



No. 17. Cyllene picta (Drury), is a very handsome beetle, so closely resembling in 

 appearance the species C. rohinicB (Forst.), which works such havoc with our 

 locusts that the beetles have been very frequently considered as the same species. There 

 are, however, structural points by which the entomologist can separate them, while 

 for others it is sufficient to know that the hickory-borer appears early in spring, and 

 that the locust-borer is found in autumn, being most abundant in September. The 

 beetle averages about three-fourths of an inch in length, and about one-fourth of an 

 inch in width. The body is black, with yellow markings, and the legs are rust-red. 

 The rounded thorax has four golden bands, formed of yellow hairs, across it, 

 and the wing-covers several waved ones of the same colour, one of which forms a very 

 distinct V/- The cream-coloured larvae of this beautiful beetle bore in every direction 

 under the bark, making extensive excavations, which are packed with the coarse saw- 

 dust-like chips made during the progress of this destructive work. 



No. 18. Xylotrechiis colonus (Fab.). This beetle is of a more cylindrical and 

 narrower shape than the preceeding, and is much smaller, measuring only from four to 

 six-tenths of an inch in length. It is of a blackish-brown colour, the wing-covers 

 having two irregular whitish bands near the base, and the tips also whitish, with a 

 large black spot on each, the black spots sometimes forming a band. I have found it 

 running on dead hickory in July. It is recorded as having been "bred from oak" by 

 Kiley, and as having been found under the bark of an old sugar maple by Mr. G. Hunt. 



No. 19. Neoclytus erythrocephalus (Fab.) is a much more slender and pretty beetle of 

 similar shape, found on felled or dead hickories during July, and has been bred from this 

 wood both by Dr. Horn and Dr. Le Conte. It is about one-third of an inch long and 

 hardly one-tenth of an inch wide, the thorax being very cylindrical and as wide as the 

 wing covers. The colour is a rusty-red, the head being of a brighter red, whence the name 

 frylhrocephahiSy from two Greek words signifying " red-head." The antennae are about 

 one-half as long as the body ; the elytra have four narrow yellow bands across them,
